As one of the trouble shooting steps for the daqd (i.e. framebuilder) I rebuilt the daqd executable. My guess is somewhere in the build code is some kind of GPS offset to make the time correct due to our lack of IRIG-B signal.
The actual daqdrc file was left untouched when I did the new install, so the symmetricom gps offset is still the same, which confuses me.
I'll take a look at the SVN diffs tomorrow to see what changed in that code that could cause a 300000000 or so offset to the GPS time.
